KNITTING-MACHINE.

SPECIFICATION formingpart of Letters Patent N 0. 670,159, dated Ma h 19,1901.

Application filed January 3,1900. Serial N0. 233. (No models To a. whomit may concern..-

Be it known that we, WILLIAM K. MILL" HOLLAND and ULYSSES GRANT LEE,citizens of the United States, and residents of Chicago, Cook county,Illinois, have invented certain new and useful Improvements in Knitting-Machines, of which the following is a specification and which areillustrated in the accom panying drawings, forming a part thereof.

I0 The invention relates to straight-knitting machines in which a pairof needleplates is mounted longitudinally upon a suitable frame and eachhaving a transverse pitch of forty-five degrees, the two plates beingspaced apart at their upper edges, so as to form the throat of themachine at which the knitting operation is performed and through whichthe fabric descends, the needles, of the hook-andiatch type, beingseated within transverse 2o grooves in the needle-plates and beingadapted to reciprocate across the throat of the machine, suitablemechanism being provided for controlling and actuating the needles andfor feeding the yarn thereto.

The objects of the invention are to generally improve machines of thistype, and more particularly to improve the mechanism for accomplishingthe fashioning of garments knitted thereon. The manner of securing 0these objects is hereinafter fully pointed out,

and the details of construction are fully illustrated in theaccompanying drawings, in which Figure l is a side elevation of themachine.

Fig. 37is a plan view of the cam-plate. Fig. 0 38 is a detailsection on the line 38 38of Fig. 28. We have shown in the drawings whatis known as a two-bed machine capable of fabricating two garmentssimultaneously and havinga frame comprisinga series of uprights 50,joined by longitudinal rails 52 and 52 and provided with a floor-plate51 and having an end plate 53 and a transverse partition 54 intermediateof its ends. A pair of needle-plates 55 55 is carried by the parts 53and too 54, the two plates being mounted upon opposite sides of themachine and inclined toward each other at an angle from the horizontalof about forty-five degrees, their upper edges being spaced apart toform the throat of the machine. These needle-plates are supported bylongitudinal rails 56, adjacent to their upper edges, and longitudinalrails 57 at their lower edges. Superimposed upon each of theneedle-plates adjacent to its upper edge is a longitudinal rail 58, andsuperimposed thereupon at its upper edge is a second longitudinal rail59. l

The two sides of the type of the machine being substantially alike, onlyone need be referred to. The cam-carriage is driven by a slide-bar 61,on which it is attached, and which each restupon the rail 58 and againstthe lower side face of the rail 59, the latter being rabbeted, so as tooverhang and guide the bar 61. The lower side of the carriage 60 ridesupon the rail 57 and against a suitable shoulder 62 formed thereon andis held in this way by a rail 63, secured to the upper face of the rail57, so as to overhang the carriage 60.

The needle plates 55 are transversely grooved, and within each groovethere is seated a needle 64, which is held to its seat by a U-shapedspring 65,reacting between the needle and the rail 58. The rearward endof each needle rests upon a needle-supporter 66, which is a short barlying within the needle-plate groove and having a finger 66 projectingthrough the needle-plate and riding upon the surface of one of thepattern-cylinders 67 68. Each needle is provided with an upstandingfinger 69 near its rearward end, adapted to be brought into engagementwith the advancing and retracting cams, which are hereinafter described.The upper edge of each needle-plate is recessed intermediate of theneedle-grooves to receive the casting-elf jacks 70, which are set insimilar recesses within the upper edge of the rail 58, being securedtherein by means of the rods 73, extending from end to end of the bed ofthe machine. A wedgebar 74 is interposed between the rearward ends ofthe jacks and the upper or front face of the rail 59.

The yarn-carrier 75 (shown only in outline in this case) spans thethroat of the machine and has downwardly-projecting feet which slide insuitable grooves in the rails 59 59, so that the carrier is adapted toreciprocate from end to end of the bed of the machine.

Power to drive the machine is transmitted to the shaft 76, journaledtransversely across the rearward portion of the frame of the machine andcarrying the fast and loose beltpulleys 77 and 78 and a pinion 79, whichinter-meshes with a gear-wheel 80, mounted upon a crank-shaft 81, fromthe crank 82 of which leads a pitman 83 to a lever 84, fulcrumed in alink 85, pivoted to a block 86, secured to the floor-plate 51. The upperend of the lever 84: is secured to a cross-head 87,

attached to the rearward ends of the slidebars 61, which drive thecam'carrier 60. In order to secure a variable stroke of thecamcarriages, the pitman 83 is attached to the lever 84 by means of ablock 88, having a pin 89, which extends through and slides in alongitudinal slot in the lever, the block also being in slidingengagement with an arm 90, which swings from a pin 91, set in the rail52. The block 88 is supported by means of a link-rod 92, to which it isadjustably secured by means of a set-screw 93, which rod is suspendedfrom one end of a rocker-arm 94, pivoted upon a stud 95, set through therail 52, the oppositeend 'of the arm 94 being provided with alaterally-projecting finger 96, which rides upon a snail-cam 97, mountedupon a shaft 98. A weight 99 is suspended from the supported end of thearm 94 by means of a rod 100, the lower end of which is provided with apiston 101, which plays in a dash-pot 102. The cam-carriage is cushionedat each end of its stroke by a double dash-pot 103, the piston-rod 104of which is secured to an arch 104, spanning the throat of the machineand secured to the two slidebars 61 61. The barrel of the dash-pot 103is provided with air-ports 105 midway between its ends.

Power is transmitted to the fashioning mechanism of the machine by meansof a shaft 106, which is driven from the shaft 81 by means of a pair ofskew-gears 107 107", mounted, respectively,upon the shafts named. A pairor take-up rollers 108 109 isjournaled below each pair of beds of themachine, these rolls being driven from the shaft 106. For this purpose apinion 110 is fixed upon the shaft, intermeshing with a pinion 11],carried by a shaft 112, journaled in the partitionplate 54 and having atits opposite end a crank-wheel 113, from the pin of which there leads apitman 114, which is pivotally connected with a lever 115, fulcrumedupon the hub of a ratchet-wheel 116, fixed upon the end of the shaft 117of the take-up rollers 108 108. The lever carries a spring-pawl 118,which coacts with the ratchet-wheel 116,

and a spring-dog 119 also engages the ratchetwheel to prevent itsbackward movement. The crank-wheel 113 is provided with a T- groove 113across its face, and the crankpin of this wheel is adjust-ably fixedwithin this groove, so that the stroke of the lever 115 may be varied.The shaft 117 is journaled in blocks 120 120, sliding in suitablebrackets 121, formed, respectively, upon the partition-plate 54 and theend plate 53, and a set-screw 122 bears against each of the blocks 120,so as to force the rollers 108 against the rollers 109 for the purposeof transmitting power to the latter.

The pattern-cylinders67 and 68 are fixed upon shafts 123 and 124, whichare journaled longitudinally as to the machine in the plates 53 and 54,and one of these shafts, as 124, is

prolonged toward the rearward end of the machine and is provided with abeveled gear 125, intermeshing with a similar gear 126, fixed upon theshaft 98, by which means the strokeadjusting mechanism alreadydescribedis controlled. Theshafts 123 and124projectthrough the plate 53, and uponthe outer ends of each there is mounted a ratchet-wheel127 128.

The pattern-cylinders 67 and 68 are driven from the shaft 106 by thefollowing mechanism: A pinion 129 is mounted upon the end of the shaftat the outside of the end plate 53 and meshes with a gear-wheel 130,which in turn meshes with a gear-wheel 131, with which there is mounteda cam-wheel 132, having enlargements 136 and 137 on its periphery. Thiscam-wheel actuates spring-controlled rock-levers 133 and 134, each ofwhich carries a spring-pawl 135 and 136, coacting, respectively, withthe ratchet-wheels 128 and 127.

The machine herein shown is especially adapted to make shirt-sleeves,such as the article covered by Letters Patent No. 644,466, granted toGeorge E. Rutledge and Ulysses G. Lee February 27, 1900, fabricatingthem from the cuff to the shoulder and widening toward the upper end ofthe sleeve. In order to accomplish the widening,it is important that thepattern-cylinders be moved alternately and each twice in succession forthe purpose of throwing in a needle first at one side of the sleeve andthen at the other, and this action is accomplished by means of the twoenlargements 136 137 on the periphery of the cam-wheel 132, so disposedthat each of the rock-levers is actuated by them successively-that is tosay, each lever is actuated twice in succession. The machine is alsoadapted to make the change automatically from the upper end of acompleted sleeve to the culf of the next sleeve, involving theinstantaneous narrowing of the fabric and the dropping of alternateneedles in order that the cuff may be knitted more openly than the upperportion of the sleeve. In making this change it is essential that theshifting of the needles in both banks be simultaneous and to that endthat both pattern-cylinders be actuated from the same rock-lever. Thisis accomplished by placing upon one of the ratchet-wheels, as 127, aplate 138, which lifts the pawl 136 out of the ratchet-teeth, therebyleaving the rock-lever 134 free to swing without advancing theratchet-wheel. A succession of ratchet-teeth 139 for the purposes forwhich the present machine is adapted, three such teeth being required,are formed in the outer disk-face of the wheel 127. An arm 140 swingsloosely upon the outer end of the shaft 123 in contact with the frontdisk face of the ratchet-wheel 127 and is connected by means of alinkbar 141 with the rock-lever 133. A pin 142 sets loosely through asuitable aperture in the arm 40, so as to impinge against the face ofthe wheel 127 and engage the ratchet-teeth 139. This pin is forcedinwardly by means of a leaf-spring 143. The teeth 139 and the plate 138are so disposed that as the pawl 136 15 lifted out of the ratchet-teethby the latter plate the pin 142 comes into engagement with the teeth139, so that as the rock-lever 133 is oscillated it advances both of thepattern-cylinders simultaneously. The linkbar 141 is shown as beingprovided with a turnbuckle, by means of which its length may be easilyadjusted.

For fabricating the particular work for which this machine s adapted itis of course necessary that the pattern-cylinders shall be at restduring such period as may be occupied in the knitting of those portionsof the sleeve which are of uniform width, and this is accomplished bythe employment of mechanism for automatically disengaging the camwheel132 from the gear-wheel 131, with which it is mounted. This cam-wheel isloosely mounted upon a stud shaft 144, fixed in the plate 53 andprojecting from its outer face and loosely carrying the gear-wheel 131.A pin 145 fits loosely in an aperture through the cam-wheel 132, itsinner end being adapted to engage a block 146, secured to the outer diskface of the gearwvheel 131, so that as this wheel is rotated thecam-wheel will be carried around with it, and the pin 145 is normallyheld in the path of this block by means of a leaf-spring 147, whichbears against its outer end. The pin 145 is withdrawn from the path ofthe block 146 by means of a rock-lever 148, one end of which rides uponthe disk face of the cam-wheel 132, its extreme end being sufficientlythin so that it will pass under the laterally-projecting head of the pin145 and its body portion becoming thickened, so that as the head of thepin rides up upon it the pin is drawn out. The farther end of therock-arm 148 rides upon the periphery of a pattern-wheel 149, which haselevated and depressed portions, the elevated portions lifting the arm148, so as to throw its opposite end out. of the path of the pin 145,and the depressed portions lowering the contacting end of the arm 148,so that its opposite end is brought into the path of this pin. By givingthe periphery of the pattern-wheel the suitable conformation the desiredmovement of the pattern-cylinders may be secured. The pattern-wheel 149is driven in the following manner: A beveled gear 150 is fixed upon theinner end of the hub of the gear-wheel131 and intermeshes with a beveledgear 151, fixed upon a shaft 152, journaled in a suitable box secured tothe inner face of the plate 53 and carrying at its lower end a worm 153,which actuates a gear-wheel154,fixed upon a shaft 155, journaled throughthe plate 53 and carrying at its outer end a pinion 156, which mesheswith theinternal gear-teeth formed on the patternwheel 149.

In order to adapt the machine for the man u- IIO facture of articles ofother forms, it is necessary to substitute for the patternwheel shown inthe drawings one having such conformation of periphery face as may bedesired, and to this end the pattern-wheels are made in annular form,with internal gearteeth for engaging the pinion 156, and are mountedupon a crescent plate 157, corresponding in diameter with the internaldiameter of the pattern-wheel and forming a bearing for the apexes ofthe gear-teeth of the latter. This crescent plate is secured to a bar160, having a T-slot, by means of a bolt 159, the bar 160 being fixed tothe plate The base of the crescent plate 157 is somewhat larger indiameter than the crescent portion and serves as a seat for the ring1&9, and a cap-plate 158, of greater diameter than the internal diameterof this ring, is secured to the outer face of the crescent plate bymeans of the bolt 159. The base of the crescent plate is aperture-d toreceive the hub of the pinion 156. The slotted bar 160 is apertured atits upper end to ac- J commodate the shaft 155 and by means of thisshaft is anchored in position, the lower end being secured by means of ascrew 161. By means of this construction pattern-wheels of varying sizesmay be applied to the machine, a crescent plate adapted to carry eachwheel being employed, and the attachment of crescent plates of differentsizes is made possible by the useof the slotted bar 160. Thisconstruction provides for a wide range of uses for the machine withoutemploying the long and cumbersome pattern chains which are commonlyfound upon knittingmachines. The carriage 60 is provided with acam-plate 162, secured to it by means of a plate 163 and carrying aV-shaped needleadvancing cam 16 and a pair of V-shaped retracting-cams165 of the usual type, these several cams being adapted to engage thelateral fingers 69 of the needles when the rearward end of the needle israised by the action of the pattern-cylinder 67 or 68.

As is well known in the art, the fabric knit-ted upon machines of thistype may be made with a loose or tight stitch by varying the position ofthe retracting-cams, the loose stitch being formed by so placing thecams that they withdraw the needles sufficiently to provide along loop,while the tight work resuits from a shorter stroke of the needles, sothat the loop is not drawn out to any length. To this end theretracting-cams 165 are secured to the plate 162 by means of headedstuds 166, passing through suitable diagonal slots in the cams, and themovement of each cam is controlled by means of a crank-pin 167, enteringa suitable transverse slot in the cam and being carried by a short shaft168, projecting upwardly through the plate 163 and being journaled in aboss 169, risingfrom the upper surface thereof.

The present machine is so organized that emits the retracting-cams maybe automatically moved for the purpose of varying the stitch in. harmonywith the variations in the pattern, and to this end the shaft 168 isprovided with a segmental worm-gear 170, intermeshing with a worm 171,fixed upon a sleeve 172, sliding upon a shaft 173 and held innon-rotative engagement therewith by means of a key-piece 174, runningin a suitable groove in the shaft. The shaft is journaled in suitablebrackets at the ends of the bed of the machine and also in a clip 175,secured to the plate 163. The shaft overhangs the end plate 53 and atits end is provided with a pinion 176, which intermeshes with a a rack177, formed on a rod 178. This rod is pivotally attached to one arm of abell-crank 179, the other end of which is connected by means ofalink-bar 180 with an arm 181, pivotally mounted upon a block 182,secured to the plate 53, to which block also the arm 148, alreadydescribed, is pivoted. The arm 181 is provided with a toe-piece 18 i,which lies in the path of a block 183, secured to the inner side face ofthe pattern-wheel 149, so that by the contact therewith of the block thearm 181 is raised, thus rocking the bell-crank 179, moving the arm 178longitudinally, turning the shaft 177, and moving the retracting-cams165. A retracting-spring 185 draws the arm 181 downwardly whendisengaged from the block 183, thereby moving the parts in the oppositedirection. By properly disposing the block 183 with reference to thepatternwheel it is obvious that the character of the stitches may bevaried as desired. An adjustable stop 186 limits the downward movementof the arm 181, so that the range of movement of the needle-cams may beadjustably fixed. The link-bar 180 is provided with a turnbuckle 187. Bylengthening or shortening this link-bar the limit to which the cams maybe moved forward is determined.

The yarn-carrier frame 75 is driven from the carriage 60, and itsconnection therewith is by means of a dog 188, pivoted upon a sleeve 189between a pair-of bracket-arms 190, rising from the yarn-carrier framesecured to the sleeve, the end of the dog falling between a pair ofshoulders 191 rising from the upper portion of the carriage 60.

The sleeve 189 is adapted to slide freely upon the shaft 192, but isprevented from rotative movement thereupon by a key 193, which engages alongitudinal groove in the shaft. The details of construction of theseparts are the same as in the case of the sleeve 172, shaft 173, and key174 and are therefore not more fully illustrated.

The shaft 192 is journaled at the ends of the bed of the machine, and atthe end which overlaps the plate 53 it is provided with a crank-arm 194,connected by means of a rigid link 195 with a spring-controlledrocker-arm 196, having its free end in the path of a cam- .block 197,fixed to the inner face of the ratchet-wheel 128, so that at eachrevolution of this ratchet-wheel the arm 1% is swung upon its pivot, soas to turn the shaft 192 sufficiently to lift the dog 188 out ofengagement with the shoulders 191, thereby permitting the yarn-carrierto remain at rest while the carriage travels in ils ordinary manner.

The rearward faces of the shoulders 191 are inclined downwardly, 'asshown at 198, so that when the dog 188 is released by the disengagementof the block 197 and the arm 196 it will be automatically raised by thecam action of the inclines 198, so as to be again brought intoengagement with the carriage 60.

The pattern-cylinders are prevented from retrogression d uring thebackward movement of the pawls 135 136 by means of the springcontrolleddogs 199 200 in engagement with them.

A hand-wheel 201 is fixed upon the shaft 76 for convenience in movingthe mechanism of the machine without the application of the belt to thefixed pulley.

The mechanism herein shown for varying the stroke of the cam-carriageforms the subject of a copending application by us, Serial No. 740,504,and the form of pattern-cylinders shown is made the subject of acopending application of George E. Rutledge and Ulysses G. Lee, SerialNo. 234, Series of 1900, and hence these features of the machine are notclaimed in this application.
